PROBLEM TO BE SOLVED: To provide a contact switch which reduces contact resistance and suppresses insertion loss. SOLUTION: The contact switch 1 includes a plurality of fixed contact electrodes 14 arranged in parallel on a substrate 11, a push rod 12 which faces to the plurality of fixed contact electrodes 14, has a plurality of contact beams 12a, and can slide within a face of the substrate 11 along an arrangement direction of the fixed contact electrodes 14, and movable contact electrodes 13 arranged on the contact beams 12a. In accordance with sliding movement of the push rod 12, the fixed contact electrode 14 and the movable contact electrode 13 are switched between in a contact state and in a non-contact state, and a transmission line 15 is mechanically connected and disconnected. A contact structure, in which groups of the fixed contact electrodes 14 and movable contact electrodes 13 (contact pairs 10) are arrayed in parallel, is achieved. While contact of all the contact pairs 10 are simultaneously and collectively conducted, the contact of the respective contact pairs 10 are independent from each other. It becomes easy to make the respective contacts contact approximately evenly at a sufficient contact pressure. COPYRIGHT: (C)2011,JPO&INPIT |
